HERBERT L. PHILLIPS, OF SEATTLE, WASHINGTON.

HAULING AND HOISTING APPARATUS.

To all whom it may concern:

Be it known that I, HERBERT L. PHILLIPS, a citizen of the United Statesof America, and a resident of the city of Seattle, in the lcounty ofKing and State of WVashington,

have invented certain new and useful Improvements in Hauling andHoisting Apparatus, of which the following is a specification.

My invention has particular reference to variable speed mechanism fortransmitting power to hauling or hoisting cables.

The primary aim of the invention is to provide a compactly arrangedmechanism of the above type embodying diiferential winding gearing, andadjustable features involving an improved application of power.

Further objects and advantages will be set forth in the followingdescription, and those features on which I desire protection, succinctlydefined in the appended claims.

With reference to the accompanying drawings, wherein similar referencecharacters designate corresponding parts throughout: Figure 1illustrates, in plan view, a preferred form of mechanism, embodying thefeatures of my invention. Fig. 2 is a front elevation of the same inpartial section. Fig. 3 is a sectional elevation, taken on line 33 ofFig. 1, and Fig. 1 illustrates a portable logging apparatus, em-

'bodying my invention, engaged in pulling a stump.

Referring now to the drawings, numeral 1 designates a drum having hubextensions journaled on a frame 3, and 2 indicates a second drumlikewise mounted on said frame and secured for rotation with a spur gear4 and a shaft 5.

Journaled in the hubs of drum 1, is a spindle 6 secured to a gear wheel7, meshing with a pinion fixedly mounted on a shaft 9, journalecl onframe 3 and secured for rotation with bevel gear wheels 10 and 11 ofunequal pitch diameters.

Meshing with wheels 10 and 11 respectively are pinions 10 and 11 looselymounted on a drive shaft 12, which may constitute the power shaft of areversible motor or engine mechanism of suitable type, designated at 13in Fig. 4c.

Pinions 10' and 11, as shown, are provlded w1th clutch counter-parts forengagement'with clutch members 10 and 11 respectively which are securedfor rotation with shaft 12 by suitable feathers or the like,

and suitably connected with respective shifters, as 10 and 11, fulcrumedon a cross piece 30 of frame 3, whereby shaft 12 may be connected witheither of said pinions.

In conjunction with spindle '6 I provide releasable means for connectingthe same with either drum 1 or 2 or with both of said drums, as may bedesired, the said means, as shown, including a double clutch member 60,slidably engaged with a squared portion 6 of spindle 6, and clutchcounter-parts 61 and 62, provided respectively on the adjacent hub ofdrum 1 and on a spur gear 40 meshing with gear 1 and bored to receivethe hub of member freely. For adjusting the clutch, just described, Ihave shown rock arms 40 and 60, mounted on frame 3 in connection withhandles 63 and 63 respectively, and having link connections withrespective rings loosely engaged in annular grooves provided in the hubsof gear 10 and member 60. By this arrangement member 60 may be adjusted,by proper manipulation of handle 63, to engage it with eithercounter-part, as may be desired, to connect spindle 6 with drum 1 orwith gear 40 to drive drum 2, and when member 60 is engaged withcounter-part 61, gear 40 may be adjusted by manipulating handle 63 toengage counter-part 62 with said member and thereby connect the spindlewith both drums. Provision is also made for operating drum 2 through themedium of helicoidal gearing which, as shown, comprises a worm wheel 50,loosely mounted on shaft 5, and a worm 51 meshing with said wheel andsecured to a shaft 52 journaled on frame 3 and rotatable with a spurgear wheel 53, meshing with a loose pinion 54 on shaft 12.

Wheel 50 and pinion 54 are each provided with suitable clutchcounter-parts for engagement with adjacent clutch members, as 50 and54:, held for rotation with shafts 5 and 12 respectively by means ofsuitable feathers or the like. Member 54 is suitably connected with ashifter 54, fulcrumed on frame part 30, and member 50 is connected, bymeans of a loose ring and links, with rock arms 55, mounted on frame 3in connection with a handle 65, as clearly shown.

The helicoidal gearing, just described, may be used as means for lockingdrum 2 from rotation in either direction by engaging clutch member 50with its counter-part on wheel 50, and when said member is thus engaged,driving connection with shaft 12 may be effected by engaging clutchmember 54: with its counter-part, as will be clearly understood. If itis desired to connect both of the drums with this gearing, gear 4L0 isconnected with spindle 6 in the manner heretofore described and clutchmember 50 con nected with wheel 50, as above set forth.

Suitable provision should be made for restraining the drums from backaction and for this purpose I have shown oppositely disposed springpressed pawls 22 and 23, pivotally mounted on frame 3 for engagementwith respective sets of ratchet teeth provided on drums 1 and 2, (seeFigs. 1 and 2). These pawls are connected with respec tive draw rods 24,having screw threaded engagement with hand wheels 25 for adjustment tomove the pawls clear of their ratchet teeth. In the case of pawl 23, thestem thereof is jointed or articulated and the outer or spring pressedportion 23 pivoted to frame 8 so that the arrangement of the adjustingmechanism just described may be the same as in the case of pawl 22.

Reference numeral 26 indicates a band wheel secured to shaft 12 andprovided with a notched flange for engagement with a dog,

as 27, pivoted on frame piece 30. Extend.-

ing about wheel 26 is a friction band 28, connected with a rock arm 28mounted on frame plece 30 and having link connection with a foot lever29 for operation to apply said band to wheel 26 when it is-desired toobtain a braking effect.

42 designates fair leaders for the cable, conveniently in the form ofrollers mounted on respective brackets 43 of frame 3 forwardly of theend portions of the drums.

In applying the apparatus as disclosed in Fig. 41, drums 1 and 2 areconnected with respective ends of the pulling cable 44, which is thenengaged with a block, as 415, made fast to the stump to be pulled.Clutch member is then shifted to engage it with counter-part 61, andmember 11 likewise connected with its counter-part on pinion 11. Poweris then applied to shaft 12 to rotate drum 1 in the direction indicatedby the arrow in Fig. 1, to take up the slack in the cable, when clutchmember 11 is thrown out and clutch member 10* engaged with itscounter-part on pinion 10 for application of the power through gearwheel 10. Should the power as thus applied be insufficient to start thestump, it may be applied with greater effect through the medium of bothdrums. In this connection it should be observed that the diameters ofdrums 1 and 2 are preferably equal while the pitch diameters of gears 40and 4: are unequal. Therefore, a difierential ulling eflfect may beobtained when the rums are connected, by operating the same to play outthe cable from drum 1 and take it up on drum 2. In

the present described oaeration, this would be efi'ected by first shiting gear 40 to engage counter-part 62 with member 60, and adjustingpawl 22 to release drum 1 for operation in a reverse direction to thatbefore described for take up of the cable.

The helicoidal gearing is especially useful where a nicety of ad ustmentis required in placing the load, as for example. when the apparatus isemployed in installing structural members, or when it is essential toimpart a slow uniform hauling motion to the drums. The application ofthe apparatus in this respect would obviously vary in accordance withexisting conditions. Assuming however, that the load-is first movedclose to a desired position by application of the power to drum 1through gear 10 and attendant mechanism, as hereinbefore described,further application of the power may be made through the helicoidalgearing to operate drum In this event, clutch members 50 and 54/ arefirst shifted to engage with their respective counter-parts and member1O shifted from engagement with its counter-part.
